ALFRED SWINGLE, OF SAN FRANCISCO, CALIFORNIA.

MACHINE FOR SHELLING PEAS.

SPECIFICATION forming part of Letters Patent No. 288,743, dated November20, 1883.

Application filed April 2, 1883. (No model.)

To all whom, it may concern:

Be it known that I, ALFRED SWINGLE, of the city and county of SanFrancisco, State of California, have invented an Improved Machine forShelling Peas; and I hereby declare the following to be a full, clear,and exact description thereof.

' Figure 1 is a longitudinal vertical section of my apparatus. Fig. 2 isa top view, andFig. 3 is a plan, of the lower belt.

A is an outer casing, suitably constructed to inclose the moving beltsand pulleys, and B is ahopper or trough adapted to dischargethe articlesto be treated upon the upper surface of the belt 0. This belt iscomposed of transverse slats supported by endless beltsor chains at eachside of the machine, and these belts pass over friction'pnlleys D D ateach end. The slats composing the surface of the belt are provided witha considerable number of wire teeth similar to those of a card. Belowthis belt'is another similar belt, E, having a slatted surface and wireteeth, but the slats are thickly perforated, the holes beingsufficiently large to allow peas to fall through when disengaged fromtheir outer coverings, and an inclined trough, F, between the surfacesof this belt receives the peas and directs them to the properreceptacle. Uponthe outer end of one of the pulley-shafts. of the upperbelt, 0, is fixed a cam, G, and an arm, H, projecting from the side ofthe casing or frame, supports an anti-friction pulley which runs in theserpentine grooveof the cam, so that when the machine is in motion theupper belt has a forward movement by means of the rotation of thepulleys and a transverse movement by the action of the cam. Theshaft-journals are fitted to their boxes so as to have an end movementto allow the cam to act. A directing-incline, I, at the rear end of theupper belt causes the peas or other articles to be treated to fall uponthe lower belt, which is somewhat the longer, and its motion, producedbya larger drivingpulley and a crossed belt, is slower and in the samedirection with the lower part of the upper belt. The peas passingbetween the two belts are thus subjected to a rolling and rubbingmovement whichspeedily divests them of their outer coverings, and theythen fall through the holes in the slats of the upper side of the lowerbelt into the trough F, while the outer coverings are carried to the endof the lower belt and deposited in asuitable receptacle at the end.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a machine for shelling peas, the combination of horizontalperforated traveling belt E, having projecting teeth,with the horizontaltoothed belt 0, means for moving the latter above the former in the samedirection and at a higher rate of speed, and means for imparting theretoa transverse vibrating motion, as set forth.

2. The horizontal traveling toothed belt 0, means. for imparting theretoa transverse vibration, the hopper B, and the inclined directing-boardI, in combination with the perforated traveling toothed belt E, andmeans for moving it below and in the same direction as, and at a slowerrate of speed than, said belt 0, as set forth.

3. The horizontally traveling and vibrating toothed belt 0 and thesubjacent perforated toothed traveling belt E, in combination with theinclined trough F, fixed between the upper .and lower parts of said beltE, as set forth.

4. The horizontal toothed traveling belts E and O, and means for movingone of them at a higher rate of speed than the other, in combinationwith the serpentine cam-roller G, the friction-roller shaft, stationaryarm H, and frame A, as set forth.

In witness whereof I hereunto set my hand.
